  1. Cogeneration

    SciTech Connect (OSTI)

    Hu, S.D.

    1985-01-01

    The purpose of this book is to assist in understanding cogeneration principles (including small power production), in evaluating cogeneration projects, and in making wise choices on cogeneration investments. Cogeneration presents an efficient way of utilizing limited energy resources because the same fuel source is used simultaneously to produce two forms of useful energy, including electricity and heat. Cogeneration also presents a good investment opportunity, for the prices of both electricity and heat and have been escalating manyfold during the past ten years. However, as with other investments, cogeneration involves market risks: the uneven and unpredictable interactions among the electric utility (the buyer), the cogenerator (the seller), and the public utility commission (the regulator) will largely determine the cogeneration market potential as well as the success of failure of many cogeneration projects. This book is intended to serve as a text on the perspicacity of cogeneration development; to identify the cogeneration market to provide guidelines on effective cogeneration system design, to evaluate cogeneration economics, to describe the electric utilities' and public utility commissions' roles in the cogeneration market, and to assist in making the cogeneration investment decision.

    Prince, R.G.H.; Poole, M.L.

    1996-12-31

    Cogeneration is a well established process for supplying heat and electricity from a single fuel source. Its feasibility and implementation in any particular case depend on technical, economic and internal and external {open_quotes}cultural{close_quotes} factors, including government policies. This paper describes the current status of small scale industrial cogeneration in Australia. A model has been developed to analyse the technical and economic aspects of retrofitting gas turbine cogeneration in the size range 3 to 30MW to industrial sites. The model demonstrates that for typical Australian energy cost data, the payback and the size of the optimized cogeneration plant depend strongly on electricity buyback prices. Also reviewed are some of the {open_quotes}cultural{close_quotes} factors which often militate against an otherwise economic installation, and government policies which may retard cogeneration by concern about local air emissions or favor it as increasing efficiency of energy use and reducing greenhouse emissions. A case study of a small gas turbine plant in Australia is outlined. 2 refs., 2 figs.

  20. Why cogeneration developers should support cogeneration deferral riders

    SciTech Connect (OSTI)

    Spiewak, S.

    1987-04-01

    The author argues that excess capacity can increase retail rates, but deferral riders which allow utilities to offer lower rates to customers who might otherwise turn to cogeneration would optimize existing generating capacity. The author notes that encouraging cogeneration is only one goal of the Public Utility Regulatory Policies Act, while efficient use of powerplant capability is of equal importance. There will still be opportunities for cogenerators under the Cogeneration Deferral Tariff if they are patient because the concept of the tariff is to defer, not preclude cogeneration.

    1996-11-01

    Chillers can be driven with cogenerated thermal energy, thereby offering the potential to increase utilization of cogeneration throughout the year. However, cogeneration decreases electric output compared to condensing power generation in power plants using a steam cycle (steam turbine or gas turbine combined cycle plants). The foregone electric production increases with increasing temperature of heat recovery. Given a range of conditions for key variables (such as cogeneration utilization, chiller utilization, cost of fuel, value of electricity, value of heat and temperature of heat recovered), how do technology alternatives for combining district cooling with cogeneration compare? This paper summarizes key findings from a report recently published by the International Energy Agency which examines the energy efficiency and economics of alternatives for combining cogeneration technology options (gas turbine simple cycle, diesel engine, steam turbine, gas turbine combined cycle) with chiller options (electric centrifugal, steam turbine centrifugal one-stage steam absorption, two-stage steam absorption, hot water absorption).

    As the result of a cooperative effort between government, industry, and a major utility, an important cogeneration project became operational in July, 1988. At the Energy Technology Engineering Center (ETEC), a research, development and testing installation operated for the United States Department of Energy (DOE), a 26.9 megawatt turbine-generator added to the SCTI facility in a bottoming-cycle configuration recovers energy from the waste steam produced in the testing steam generators. This paper reports on this project, called Power Pak, which originated in 1980 with proposals to DOE for funding of a cogeneration addition, and encouragement by DOE to evaluate and pursue this and other energy conservation measures. This article presents a narrative history of the development of this project with lessons learned.

    Cogeneration is the simultaneous generation of two types of energy, usually electricity and thermal energy, from a single energy source such as natural gas or diesel fuel. Cogeneration systems can be twice (or more) as efficient than conventional energy systems since both the electricity and the available thermal energy produced as a by-product of the electric generation, are used. This study identified cogeneration technologies and equipment capable of meeting Department of Defense (DOD) requirements for generation of electrical and thermal energy and described a wide range of successful cogeneration system configurations potentially applicable to DOD energy plants, including: cogeneration system prime movers, electrical generating equipment, heat recovery equipment, and control systems. State of the art cogeneration components are discussed in detail along with typical applications and analysis tools that are currently available to assist in the evaluation of potential cogeneration projects. A basic analysis was performed for 55 DOD installations to determine the economic benefits of cogeneration to the DOD. The study concludes that, in general, cogeneration systems can be a very cost effective method of providing the military with its energy needs.

    Leading industrial companies and institutions are forever seeking new and better ways to reduce their expenses, reduce waste, meet environmental standards, and, in general, improve their bottom-line. One approach to achieving all of these goals is a 100 year-old concept, cogeneration. Many industrial and institutional plants need thermal energy, generally as steam, for manufacturing processes and heating. They also need electric power for motors, lighting, compressed air and air conditioning. Traditionally, these fundamental needs are met separately. Steam is produced with industrial boilers and electricity is purchased from a local utility company. However, these needs can be met at the same time with cogeneration, using the same heat source. Cogeneration is the concurrent production of electrical power and thermal energy from the same heat source. Large steam users commonly take advantage of cogeneration by using high pressure steam with a back pressure turbine to generate electricity, and extract lower pressure steam from the turbine exhaust for their process needs. This approach reduces their electric utility bills while still providing thermal energy for industrial processes. The result is also a more efficient process that uses less total heat and discharges less smoke up the stack. Newer technologies are making cogeneration opportunities available to smaller-sized thermal plants, and electric utility deregulation opportunities are causing many CEOs to seriously consider cogeneration in their manufacturing plants. Whether steam is created through cogeneration or separate generation, many opportunities exist to improve productivity in the distribution system, operation, and maintenance. These opportunities are captured by taking a systems approach, which is promoted by programs such as the Department of Energy's Steam Challenge.

    Cogeneration, also known as combined heat and power (CHP), is the combined sequential generation of electricity and thermal or electric energy. The technology has been known essentially since the first commercial generation of electricity as a high efficiency technology option. After a period of decline, its use increased significantly during the 1980s and it is receiving renewed interest lately as a means of increasing efficiency and reducing emissions of air pollutants including carbon emissions. New and developing technology options have added to this potential. Forecasts of future growth and efforts to stimulate cogeneration need to take into account the history of the technology, the factors that have driven it in the past, and factors which could stimulate or retard future growth. This paper reviews and analyzes these factors and looks toward the future potential for cogeneration.

  19. Cooling tower environmental considerations for cogeneration projects

    SciTech Connect (OSTI)

    Weaver, K.L.; Putnam, R.A.; Schott, G.A.

    1994-12-31

    Careful consideration must be given to the potential environmental impacts resulting from cooling tower operations in cogeneration projects. Concerns include visible plumes, fogging and icing of nearby roadways, emissions, water use, aesthetics, and noise. These issues must be properly addressed in order to gain public acceptance and allow for easier permitting of the facility. This paper discusses the various evaporative type cooling tower technologies from an environmental standpoint. In addition, typical concerns and questions raised by the public are presented, along with suggested guidelines for addressing these concerns. The use of modeling to predict the potential environmental impacts from cooling tower operations is sometimes required by regulatory agencies as a condition for obtaining approval for the facility. This paper discusses two of the models that are currently available for predicting cooling tower environmental impacts such as fogging, icing, salt deposition, and visible plumes. The lack of standardized models for cooling tower noise predictions, and the means by which the modeling requirements may be achieved are also addressed. An overview of the characteristics of cooling tower noise, the various measures used for noise control and the interdependency of the control measures and other cooling tower performance parameters are presented. Guidance is provided to design cost effective, low noise installations. The requirements for cooling tower impact assessments to support permitting of a cogeneration facility are also presented.

The proposed solar cogeneration system is expected to save the equivalent of approximately 10,500 barrels of fuel oil per year and to involve low development risks. The site and existing plant are described, including the climate and plant performance. The selection of the site-specific configuration is discussed, including: candidate system configurations; technology assessments, including risk assessments of system development, receiver fluids, and receiver configurations; system sizing; and the results of trade studies leading to the selection of the preferred system configuration.

    Cogeneration is a name given to energy systems that produce both electric power and useful thermal energy such as steam. While cogeneration markets have flourished in California, Texas, and some states, those in Maryland have not. A primary reason is that the industries that have been targeted in other states--e.g., oil refining, pulp and paper, chemicals, food processing--are not major elements of Maryland's industrial base. The study estimates the potential for future cogeneration in Maryland, both large units and small packaged systems, and assesses the potential impact of cogeneration systems on Maryland's energy needs between now and 2005. The study is presented in three volumes. Because of significant differences between large- and small-scale cogeneration, the analysis of these two systems was performed separately. This volume is a summary document presenting the findings from both studies.

    China`s energy production is largely dependent on coal. China currently ranks third in global CO{sub 2} emissions, and rapid economic expansion is expected to raise emission levels even further in the coming decades. Cogeneration provides a cost-effective way of both utilizing limited energy resources and minimizing the environmental impacts from use of fossil fuels. However, in the last 10 years state investments for cogeneration projects in China have dropped by a factor of 4. This has prompted this study. Along with this in-depth analysis of China`s cogeneration policies and investment allocation is the speculation that advanced US technology and capital can assist in the continued growth of the cogeneration industry. This study provides the most current information available on cogeneration development and market potential in China.

  16. Analysis of Homogeneous Charge Compression Ignition (HCCI) Engines for Cogeneration Applications

    SciTech Connect (OSTI)

    Aceves, S; Martinez-Frias, J; Reistad, G

    2004-04-30

    This paper presents an evaluation of the applicability of Homogeneous Charge Compression Ignition Engines (HCCI) for small-scale cogeneration (less than 1 MWe) in comparison to five previously analyzed prime movers. The five comparator prime movers include stoichiometric spark-ignited (SI) engines, lean burn SI engines, diesel engines, microturbines and fuel cells. The investigated option, HCCI engines, is a relatively new type of engine that has some fundamental differences with respect to other prime movers. Here, the prime movers are compared by calculating electric and heating efficiency, fuel consumption, nitrogen oxide (NOx) emissions and capital and fuel cost. Two cases are analyzed. In Case 1, the cogeneration facility requires combined power and heating. In Case 2, the requirement is for power and chilling. The results show that the HCCI engines closely approach the very high fuel utilization efficiency of diesel engines without the high emissions of NOx and the expensive diesel fuel. HCCI engines offer a new alternative for cogeneration that provides a unique combination of low cost, high efficiency, low emissions and flexibility in operating temperatures that can be optimally tuned for cogeneration systems. HCCI engines are the most efficient technology that meets the oncoming 2007 CARB NOx standards for cogeneration engines. The HCCI engine appears to be a good option for cogeneration systems and merits more detailed analysis and experimental demonstration.

    The utilities required to satisfy the university`s electrical, steam and chilled water needs are generated at the cogeneration facility located in the center of the main campus. The building housing this cogeneration facility was constructed in 1909, at this time it contained a cogeneration facility. The original facility produced 1/100 the capacity of the new facility, yet it was housed in the same area. This existing facility burned coal until April 16, 1932, when the last coal train to pass through the campus on the Colorado and Southern tracks whistled at the campus crossing at 8:45 in the evening. This signaled the end to the cogeneration era at the Boulder campus until September 27, 1992, when once again the university began commercial operation of the new cogeneration facility. Implementation of the Public Utilities Regulatory Policy Act of 1978 (PURPA) encouraged the development of cogeneration facilities due to their inherent energy efficiency. The federal government encouraged the development of cogeneration facilities by removing several major obstacles that historically deterred its full development. It was because of this act, coupled with the fact that the university is interested in energy conservation, reliable energy supply, has a large utility load and wishes to save money that they proceeded with their project. The paper describes the cogeneration system process and power options.

  10. Cogeneration system selection using the Navy's CELCAP code

    SciTech Connect (OSTI)

    Lee, T.Y.R.

    1988-08-01

    The performance of a cogeneration system is easily affected by several factors; number and type of engines used in the system, the manner in which the system is operated, and the electric and thermal load profile that the system has to supply. Other factors which the energy analyst must also consider are the electric utility rate structure, the price of fuel used in the cogeneration system, and the working habits of the people at the site. The evaluation of cogeneration energy systems for the purpose of selecting a configuration with the best performance requires a great amount of effort. A computer program to analyze a cogeneration system would greatly reduce the effort needed to evaluate cogeneration systems. Realizing the need for such a tool, the Naval Civil Engineering Laboratory developed such a cogeneration analysis computer program, Civil Engineering Laboratory Cogeneration Analysis Program (CELCAP), for the purpose of evaluating the performance of cogeneration systems on a life-cycle operating cost basis.

    1998-07-01

    Cogeneration due to potentially high efficiency can be very competitive in a deregulated market. Cogeneration can achieve extremely high levels of thermal efficiency, much higher than the most advanced and sophisticated combined cycle power plants generating only electric power. Thermal efficiency is one of the key factors in determining the power plant economics and feasibility. High efficiency means a lesser amount of fuel is used to generate the same amount of energy. In turn, burning a lesser amount of fuel means that fewer pollutants will be emitted. The paper first describes cogeneration plants, then discusses the importance of thermal load availability, cogeneration and distributed generation and other issues affecting cogeneration.

  2. Thermal tracking cogeneration -- A new or old idea? Cogeneration for multi-thermal loads

    SciTech Connect (OSTI)

    Geers, J.R.

    1998-04-01

    The idea of designing a cogeneration project that produces electricity based on the existing heating load is common to many cogeneration projects, but may be limiting the ultimate potential to the end user. Cogeneration which is developed as a power generator producing a small amount of steam for a host load is also common. However, the idea of designing a cogeneration facility to track multiple utility loads is not as common. Where the concept has been used, the projects have been very successful. This article has been written as a primer for professionals looking for ideas when performing analysis of a potential cogeneration project, and as a thought-provoker for end users. The authors will look at each of the possible loads, outline various technical considerations and factors, look at the factors impacting the economics, and lay out an approach that would provide assistance to those trying to analyze a cogeneration project without specialized engineering assistance. Regulatory, legal and financing issues are covered in other sources.

    1995-12-01

    Cogeneration systems fueled by natural gas exceed the reliability of most central station power generating units, according to a study conducted by RINC Corporation for Gas Research Institute (GRI). In the study, researchers obtained operating data from 122 natural gas cogeneration units nationwide representing 2,200 megawatts (MW) of capacity and nearly 2 million hours of operating time at 37 facilities. Units were grouped into categories reflecting size (from 60 kilowatts to 100 MW), type of system (gas engine or gas turbine technology), use of emission controls, and type of thermal application. Various types and sizes of gas systems reported average availability factors ranging from 90.0 to 95.8 versus a weighted average of 85.9 percent for fossil-fuel steam, nuclear, and gas-turbine-based central station power generating units. Comparisons are based on study data and data reported by the North American Electric Reliability Council for utility power plants. Gas cogeneration can improve utility operations because as a group the relatively small, dispersed cogeneration units are more reliable than one or more large central station units of similar capacity.

  4. The success of cogeneration in Europe

    SciTech Connect (OSTI)

    Hunschofsky, H.

    1998-10-01

    The European engineers take a different approach to designing cogeneration plants. Instead of building large gas turbines or combined cycle plants whose main target is to produce electricity and then trying to utilize as much heat as possible, European engineers target the replacement of the base heat supply of certain, small scale entities. By focusing on the annual heat demand graph, the basic layout for maximum utilization is determined. If a plant can use all or a majority of the electricity, the by-product, produced in this combined process, the perfect requirements are a given. Today cogeneration is one of the prime technologies available to achieve two valuable goals: efficient usage of limited resources and air pollution reduction. In every major European country there is a non-profit organization promoting the usage of cogeneration and acting as a platform for the various interests involved. These national institutions are members of Cogen Europe, a non-profit organization based in Brussels, Belgium, whose main focus is to promote cogeneration to a multinational level.

  5. Cogeneration in the former Soviet Union

    Horak, W.C.

    1997-07-01

    The former Soviet Union made a major commitment to Cogeneration. The scale and nature of this commitment created a system conceptually different from Cogeneration in the west. The differences were both in scale, in political commitment, and in socio economic impact. This paper addresses some of the largest scale Cogeneration programs, the technology, and the residual impact of these programs. The integration of the Cogeneration and nuclear programs is a key focus of the paper. Soviet designed nuclear power plants were designed to produce both electricity and heat for residential and industrial uses. Energy systems used to implement this design approach are discussed. The significant dependence on these units for heat created an urgent need for continued operation during the winter. Electricity and heat are also produced in nuclear weapons production facilities, as well as power plants. The Soviets also had designed, and initiated construction of a number of nuclear power plants {open_quotes}ATETs{close_quotes} optimized for production of heat as well as electricity. These were canceled.

    The Pacific Northwest Laboratory (PNL) leads the U.S. Department of Energy`s Thermal Energy Storage (TES) Program. The program focuses on developing TES for daily cycling (diurnal storage), annual cycling (seasonal storage), and utility-scale applications [utility thermal energy storage (UTES)]. Several of these storage technologies can be used in a new or an existing power generation facility to increase its efficiency and promote the use of the TES technology within the utility and the industrial sectors. The UTES project has included a study of both heat storage and cool storage systems for different utility-scale applications. The study reported here has shown that an oil/rock diurnal TES system, when integrated with a simple gas turbine cogeneration system, can produce on-peak power for $0.045 to $0.06 /kWh, while supplying a 24-hour process steam load. The molten salt storage system was found to be less suitable for simple as well as combined-cycle cogeneration applications. However, certain advanced TES concepts and storage media could substantially improve the performance and economic benefits. In related study of a chill TES system was evaluated for precooling gas turbine inlet air, which showed that an ice storage system could be used to effectively increase the peak generating capacity of gas turbines when operating in hot ambient conditions.

  12. BP Cherry Point Cogeneration Project, Draft Environmental Impact Statement

    SciTech Connect (OSTI)

    2003-09-19

    BP West Coast Products, LLC (BP or the Applicant) proposes to construct and operate a nominal 720-megawatt (MW), natural-gas-fired, combined-cycle cogeneration facility next to the existing BP Cherry Point Refinery in Whatcom County, Washington. The Applicant also owns and operates the refinery, but the cogeneration facility and the refinery would be operated as separate business units. The cogeneration facility and its ancillary infrastructure would provide steam and 85 MW of electricity to meet the operating needs of the refinery and 635 MW of electrical power for local and regional consumption. The proposed cogeneration facility would be located between Ferndale and Blaine in northwestern Whatcom County, Washington. The Canadian border is approximately 8 miles north of the proposed project site. The Washington State Energy Facility Site Evaluation Council (EFSEC) has jurisdiction over the evaluation of major energy facilities including the proposed project. As such, EFSEC will recommend approval or denial of the proposed cogeneration facility to the governor of Washington after an environmental review. On June 3, 2002, the Applicant filed an Application for Site Certification (ASC No. 2002-01) with EFSEC in accordance with Washington Administrative Code (WAC) 463-42. On April 22, 2003, the Applicant submitted an amended ASC that included, among other things, a change from air to water cooling. With the submission of the ASC and in accordance with the State Environmental Policy Act (SEPA) (WAC 463-47), EFSEC is evaluating the siting of the proposed project and conducting an environmental review with this Environmental Impact Statement (EIS). Because the proposed project requires federal agency approvals and permits, this EIS is intended to meet the requirements under both SEPA and the National Environmental Policy Act (NEPA). The Bonneville Power Administration (Bonneville) and U.S. Army Corps of Engineers (Corps) also will use this EIS as part of their respective decision-making processes associated with the Applicant's request to interconnect to Bonneville's transmission system and proposed location of the project within wetland areas. Therefore, this Draft EIS serves as the environmental review document for SEPA and for NEPA as required by Bonneville for the interconnection and the Corps for its 404 individual permit. The EIS addresses direct, indirect, and cumulative impacts of the proposed project, and potential mitigation measures proposed by the Applicant, as well as measures recommended by EFSEC. The information and resulting analysis presented in this Draft EIS are based primarily on information provided by the Applicant in the ASC No. 2002-01 (BP 2002). Where additional information was used to evaluate the potential impacts associated with the proposed action, that information has been referenced. EFSEC's environmental consultant, Shapiro and Associates, Inc., did not perform additional studies during the preparation of this Draft EIS.

    1996-06-01

    In order to understand the benefits of cogeneration -- the on site production of electricity and hot water -- it is beneficial to know the overall efficiency of the energy media presently being used when compared to cogeneration. Virtually every commercial and industrial establishment purchases their electricity from the local utility company and heat their water by using on site boilers and hot water heaters fired by natural gas or propane -- which they also purchase from an outside supplier. When on-site cogeneration is compared to purchased power the results in fuel usage efficiency are: cogeneration -- 89.2%; purchased power -- 52.6%. The overall result of on site, properly applied cogeneration is an economical, environmental, and conservational tool that preserves an establishment`s cash, helps reduce pollution and conserves a precious natural resource.

  11. Improving cogeneration plant performance through effective maintenance strategies

    SciTech Connect (OSTI)

    Sheikh, S.M.

    1998-12-31

    Gas-fired cogeneration plants supplying power and thermal energy make up an increasing percentage of new fossil generation capacity additions, both in the US and overseas. These plants are popular, not only because they cost less to build, but also because they are highly efficient and their operation and maintenance costs are lower than plants using the traditional coal-based Rankine cycle. One of the methods being used to contain the initial cost of building cogeneration plants is to minimize redundancy both in the quantity of spare equipment specified for the various systems in the plants and in the design capacity of individual components. The overall effect of such a strategy may lead to reduced reliability and availability of the cogeneration plant in the long term. Operating cogeneration plants present a variety of technologies, equipment, and operating practices. While newer cogeneration plants routinely operate at a reliability of 90% or higher, older plants may not be able to achieve such performance due to excessive equipment breakdowns or inadequate maintenance strategies. By not having the appropriate maintenance programs in place, even newer cogeneration plants are vulnerable to deteriorating reliability and availability in the long term. This paper describes mechanisms for directing maintenance resources toward reducing current maintenance costs while maintaining high availability without sacrificing long-term reliability. The maintenance strategies discussed are those that can provide the maximum benefits for improving cogeneration plant reliability, availability, capacity, cost control, and safety.

    Hunschofsky, H.

    1998-07-01

    Cogeneration, the utilization of heat created while producing electricity from fossil fuels, is by no means a new technology. In 1926, 71 years ago, a brochure from MAN in Germany showed a heat recovery system for diesel engines. Despite the fact that cogeneration has existed for a long time, it took half a century and the first so called ``oil crisis'' in the 1970's for societies to become aware of limited energy resources. Environmental groups gave cogeneration an additional boost in the 1980's. Additionally, governments in the Western European Nations attracted cogeneration investors by not only providing subsidies and tax breaks but also regulating electricity prices. Although there has been much growth in the cogeneration market in the past years, the industry has still not reached its peak in Europe. A variety of studies have shown that there is still significant growth potential in the future: WWF (World Wildlife Fund) published a study in 1996 suggesting a target of 330 Twh of generation will be produced through cogeneration by the year 2005, a tripling of current generation. Due to the EU's belief that cogeneration is an optimal form of generation, it has developed a cogeneration strategy. As part of this strategy, the EC is promoting cogeneration so that it accounts for 20% of all European generation by the year 2010. These factors would give a variety of companies such as equipment suppliers, investment companies, utilities, consultants and energy brokers a wide range of opportunities in Europe. Detailed information and some hints will be given as to how to participate in this fast growing industry. Ways to overcome obstacles in those markets will be shown as well as the pros and cons of different entry strategies.

    Through the Urban Integrated Industrial Cogeneration Systems Analysis (UIICSA), the City of Chicago embarked upon an ambitious effort to identify the measure the overall industrial cogeneration market in the city and to evaluate in detail the most promising market opportunities. This report discusses the background of the work completed during Phase II of the UIICSA and presents the results of economic feasibility studies conducted for three potential cogeneration sites in Chicago. Phase II focused on the feasibility of cogeneration at the three most promising sites: the Stockyards and Calumet industrial areas, and the Ford City commercial/industrial complex. Each feasibility case study considered the energy load requirements of the existing facilities at the site and the potential for attracting and serving new growth in the area. Alternative fuels and technologies, and ownership and financing options were also incorporated into the case studies. Finally, site specific considerations such as development incentives, zoning and building code restrictions and environmental requirements were investigated.

    As a case study of the environmental feasibility of a major renovation to the University of Minnesota`s steam service facilities demonstrates, cogeneration is an efficient method of energy production and reduces area-wide air emissions by reducing the demand and production levels at less efficient facilities in the region. To acknowledge this benefit and encourage efficient production, {open_quotes}cogeneration credits{close_quotes} should be granted to energy producers as an offset to point-source emissions. This paper will identify the projected reduction in area-wide emissions for the University`s cogeneration project and alternatives and will demonstrate the method used for calculating those emissions. Although regulators have not yet fully accepted the validity of cogeneration credits, attitudes are starting to change, and we can only persuade regulators to encourage efficient production by discussing the issue now and by developing ways to make these ideas effective.

    1993-03-01

    This article describes a means for industrial, institutional, and commercial energy users to reduce their costs through increased energy efficiency while providing resource management and environmental benefits. There is a significant opportunity for industrial, institutional, and commercial energy users to reduce their costs through the development of internal-use cogeneration systems. These cost reductions are the direct result of increased energy efficiency, providing both resource management and environmental benefits. While internal-use cogeneration may be cost effective, the development of the full potential for this option is hindered by electric utility resistance and counter-marketing and by the neglect of many state regulatory bodies. If the end user is to reap the benefits of this option, then he must develop an understanding of the technology and the developmental process, formulate reasonable expectations as to the benefits of cogeneration, and step forward to provide the initiative required to obtain those benefits. Similarly, the cogeneration industry must recognize the unique developmental issues that arise within the context of small displacement projects and develop the required engineering, financing, construction, and operating infrastructure. Finally, regulators must allow internal-use cogeneration to achieve its full, free-market potential.

  5. Evaluating the economic effectiveness of a cogeneration plant

    SciTech Connect (OSTI)

    Korik, L.; Yeaple, D.: Hajosy, M.

    1996-08-01

    Economic considerations constitute the major factor in the decision to build a cogeneration plant and to its eventual design - topics which have been the focus of many studies and papers. These economic concerns continue when the plant is built and on-line, thus plant operation must be geared to provide the customers` demand in the most economically effective manner possible. Unfortunately, the complexity of and high degree of interaction between the disparate components of a cogeneration plant oftentimes, make it difficult to conceptualize the plant configuration required to maximize plant economic performance for a given demand, Indeed, actions taken to increase the thermal performance of individual plant components can actually decrease the overall economic effectiveness of the plant as a whole in the context of converting fuels to sendouts. What is needed, then, is a way to meld the performance of individual plant components into a total plant performance index that accurately measures the economic effectiveness of the plant. This paper details such a method developed by the Cogeneration Management Company to accomplish the performance evaluation of its Medical Area Total Energy Plant which supplies electricity, steam, and chilled water to the Longwood. Medical Area in Boston, This method - which is easily adapted to a variety of cogeneration designs - addresses the aforementioned complexities in the assessing of a cogeneration plant`s effectiveness and results in simple-to-understand plant performance quantifications which have proved to be of great utility in ensuring the economically sound operation of MATEP.

Because of commercial pressures, building owners and cogeneration companies are keen to reduce the time and money involved in sizing units, and a decision support tool has been developed to aid the engineer in selecting the unit size. An initial assessment of the sizing can be made with only knowledge of the building`s type, size, and location, which enables the model to be used in new build situations. For an existing building, the accuracy of the predictions can then be progressively improved by providing more information about the building`s energy use, enabling the optimum unit to be identified. This paper briefly describes the model and demonstrates its use through an example feasibility study.

  8. Tomorrow`s energy today for cities and counties: Cogeneration powers up cost-competitive energy

    SciTech Connect (OSTI)

    1995-11-01

    Cities and counties build many multi-million dollar facilities, and supplying energy to run these facilities is a long-term obligation for a community. Cogeneration offers local governments an opportunity to reduce the cost of providing electricity, heating, and cooling to their buildings. Sometimes cogeneration is combined with district heating and cooling systems. This kind of cogeneration results in system efficiencies as high as 70%--about twice the efficiency of a conventional power plant that produces only electricity! The article describes cogeneration combined with district cooling in Trenton, NJ, and cogeneration on a small scale in San Jose, California.

    A methodology for performance evaluation of a combined-cycle cogeneration system has been presented. Results for such a system using an advanced gas-turbine as the prime mover show that it is a very versatile system. It can produce a large power-to-heat ratio together with a high second-law efficiency over a wide range of process steam pressures. This work also demonstrates once again that the most appropriate and useful performance parameters for decision-making in cogeneration system design are the second-law efficiency and the power-to-heat ratio.

    General Electric's method of steam turbine performance was used with pure electrical and with cogeneration power plants at various flow rates. Comparisons were made for two cases: (1) the same amount of heat is added to each boiler and the amount of electrical power generated is compared; and (2) when each plant should produce the same amount of electric power and the amount of heat added to each boiler is compared. Cogeneration is energetically more efficient than pure electrical plant. Correlations for the dependence of heat rate, power generated, heat added to throttle flow ratio were obtained from this work.

    Uncertainty evaluation constitutes a key feature of BEPU (Best Estimate Plus Uncertainty) process. The uncertainty can be the result of a Monte Carlo type analysis involving input uncertainty parameters or the outcome of a process involving the use of experimental data and connected code calculations. Those uncertainty methods are discussed in several papers and guidelines (IAEA-SRS-52, OECD/NEA BEMUSE reports). The present paper aims at discussing the role and the depth of the analysis required for merging from one side suitable experimental data and on the other side qualified code calculation results. This aspect is mostly connected with the second approach for uncertainty mentioned above, but it can be used also in the framework of the first approach. Namely, the paper discusses the features and structure of the database that includes the following kinds of documents: 1. The' RDS-facility' (Reference Data Set for the selected facility): this includes the description of the facility, the geometrical characterization of any component of the facility, the instrumentations, the data acquisition system, the evaluation of pressure losses, the physical properties of the material and the characterization of pumps, valves and heat losses; 2. The 'RDS-test' (Reference Data Set for the selected test of the facility): this includes the description of the main phenomena investigated during the test, the configuration of the facility for the selected test (possible new evaluation of pressure and heat losses if needed) and the specific boundary and initial conditions; 3. The 'QR' (Qualification Report) of the code calculation results: this includes the description of the nodalization developed following a set of homogeneous techniques, the achievement of the steady state conditions and the qualitative and quantitative analysis of the transient with the characterization of the Relevant Thermal-Hydraulics Aspects (RTA); 4. The EH (Engineering Handbook) of the input nodalization: this includes the rationale adopted for each part of the nodalization, the user choices, and the systematic derivation and justification of any value present in the code input respect to the values as indicated in the RDS-facility and in the RDS-test.

    1995-12-01

    An optimal operational planning method is proposed for cogeneration systems with thermal storage. The daily operational strategy of constituent equipment is determined so as to minimize the daily operational cost subject to the energy demand requirement. This optimization problem is formulated as a large-scale mixed-integer linear programming one, and it is solved by means of the decomposition method. Effects of thermal storage on the operation of cogeneration systems are examined through a numerical study on a gas engine-driven cogeneration system installed in a hotel. This method is a useful tool for evaluating the economic and energy-saving properties of cogeneration systems with thermal storage.

  4. Small-scale biomass fueled cogeneration systems - A guidebook for general audiences

    SciTech Connect (OSTI)

    Wiltsee, G.

    1993-12-01

    What is cogeneration and how does it reduce costs? Cogeneration is the production of power -- and useful heat -- from the same fuel. In a typical biomass-fueled cogeneration plant, a steam turbine drives a generator, producing electricity. The plant uses steam from the turbine for heating, drying, or other uses. The benefits of cogeneration can mostly easily be seen through actual samples. For example, cogeneration fits well with the operation of sawmills. Sawmills can produce more steam from their waste wood than they need for drying lumber. Wood waste is a disposal problem unless the sawmill converts it to energy. The case studies in Section 8 illustrate some pluses and minuses of cogeneration. The electricity from the cogeneration plant can do more than meet the in-house requirements of the mill or manufacturing plant. PURPA -- the Public Utilities Regulatory Policies Act of 1978 -- allows a cogenerator to sell power to a utility and make money on the excess power it produces. It requires the utility to buy the power at a fair price -- the utility`s {open_quotes}avoided cost.{close_quotes} This can help make operation of a cogeneration plant practical.

    SciTech Connect (OSTI)

    Vincent, J.W.

    1982-01-01

    In February of 1980 the Federal Energy Regulatory Commission (FERC) promulgated a set of rules that were to commence the implementation process of Section 210 of the Public Utility Regulatory Policies Act of 1978 (PURPA). Of particular interest to economists are the pricing provisions in the rules that pertain to integrating dispersed sources of electric power generation into conventional electric utility systems. The full avoided cost pricing provision couples a utility mandate to purchase power from qualified dispersed facilities (cogenerators, wind power, small hydro facilities, etc., hereafter denoted QFs) with the requirement that the price the utility pays for such purchases be equal to the full extent of the cost it avoids by not generating the power itself. The simultaneous purchase and sale billing scheme requires a utility to purchase the gross power output of a QF at the full avoided cost rate and simultaneously sell back to the QF its power requirement on the applicable retail tariff. Theoretical investigation of these two provisions reveals that, properly defined, they are consistent with improving economic signals with respect to electricity generation.

    The Department of Energy, under the Clean Coal Technology program, proposes to provide cost-shared financial assistance for the construction of a utility-scale circulating fluidized bed technology cogeneration facility by York County Energy Partners, L.P (YCEP). YCEP, a project company of ir Products and Chemicals, Inc., would design, construct and operate a 250 megawatt (gross) coal-fired cogeneration facility on a 38-acre parcel in North Codorus Township, York County, Pennsylvania. The facility would be located adjacent to the P. H. Glatfelter Company paper mill, the proposed steam host. Electricity would be delivered to Metropolitan Edison Company. The facility would demonstrate new technology designed to greatly increase energy efficiency and reduce air pollutant emissions over current generally available commercial technology which utilizes coal fuel. The facility would include a single train circulating fluidized bed boiler, a pollution control train consisting of limestone injection for reducing emissions of sulfur dioxide by greater than 92 percent, selective non-catalytic reduction for reducing emissions of nitrogen oxides, and a fabric filter (baghouse) for reducing emissions of particulates. Section II of this report provides a general description of the facility. Section III describes the site specifics associated with the facility when it was proposed to be located in West Manchester Township. After the Cooperative Agreement was signed, YCEP decided to move the proposed site to North Codorus Township. The reasons for the move and the site specifics of that site are detailed in Section IV. This section of the report also provides detailed descriptions of several key pieces of equipment. The circulating fluidized bed boiler (CFB), its design scale-up and testing is given particular emphasis.

    An experimental observation of spatiotemporal evolution of dust density waves (DDWs) in cogenerated dusty plasma in the presence of modified field induced by glass plate is reported. Various DDWs, such as vertical, oblique, and stationary, were detected simultaneously for the first time. Evolution of spatiotemporal complexity like bifurcation in propagating wavefronts is also observed. As dust concentration reaches extremely high value, the DDW collapses. Also, the oblique and nonpropagating mode vanishes when we increase the number of glass plates, while dust particles were trapped above each glass plates showing only vertical DDWs.

    The Waste-to-Energy Cogeneration Project at Centennial Park has allowed methane from the closed Centennial landfill to export excess power into the the local utility’s electric grid for resale. This project is part of a greater brownfield reclamation project to the benefit of the residents of Munster and the general public. Installation of a gas-to-electric generator and waste-heat conversion unit take methane byproduct and convert it into electricity at the rate of about 103,500 Mwh/year for resale to the local utility. The sale of the electricity will be used to reduce operating budgets by covering the expenses for streetlights and utility bills. The benefits of such a project are not simply financial. Munster’s Waste-to Energy Cogeneration Project at Centennial Park will reduce the community’s carbon footprint in an amount equivalent to removing 1,100 cars from our roads, conserving enough electricity to power 720 homes, planting 1,200 acres of trees, or recycling 2,000 tons of waste instead of sending it to a landfill.

    This report describes a two-phase energy project currently contemplated for joint implementation at the Victorias Milling Company, a large sugar mill and refinery on the island of Negros in the Visayas region of the Philippines. The Energy Efficiency (EE) phase is expected to reduce of eliminate VMC`s fossil fuel consumption, which will have a direct and substantial impact on carbon emissions. Phase I is an EE project which involves the installation of equipment to reduce steam and electricity demand in the factories. Phase II, will involve retrofitting and increasing the capacity of the steam and power generation systems, and selling power to the grid. By increasing efficiency and output, the cogeneration project will allow the factory to use only bagasse sugar cane fiber waste as fuel for energy needs. The cogeneration project will also eliminate VMC`s electricity purchases and supply additional power for the island, which will offset generation capacity expansion on the island and the Visayas region.

In particular, we extend results of Gomilko and Brenner, Thomee and show that polynomial boundedness of a semigroup implies polynomial boundedness of its cogenerator. As is shown by an example, the result is optimal. For analytic semigroups we show that the converse holds, i.e., polynomial boundedness of the cogenerators implies polynomial boundedness of the semigroup.

    The author describes the development of the cogeneration system at the University of Colorado at Boulder campus, which was brought on line in 1992. The author reviews the history of power and utilities services for the campus. Prior to 1932, the campus maintained a coal fired cogeneration facility. In the 1980`s, evaluation of existing systems on campus, and changes in regulations for public utilities, prompted the campus to implement a new cogeneration facility, housed in the building originally used for this purpose. This facility allows the university to control this aspect of its needs, provides cheaper utilities, and allows the university to be directly involved in energy conservation.

    The design, operation, performance, economics and energy efficiency of the 25,000 kW co-generating power plant at the Mead Co. paper mill in Kingsport, TN are described, and compared with the efficiency of producing only process heat at the plant while importing electric power from a local utility. It was established that on-site co-generation consumed 2/3 of the energy that would have been required for on-site process heat generation plus purchased off-site-generated electric power and that co-generation resulted in more than $2.8 million saved during the period from 1975 through 1978.

    Within several projects we investigated grid structures and management strategies for active grids with high penetration of renewable energy resources and distributed generation (RES and DG). Those ''smart grids'' should be designed and managed by model based methods, which are elaborated within these projects. Cogeneration plants (CHP) can reduce the greenhouse gas emissions by locally producing heat and electricity. The integration of thermal storage devices is suitable to get more flexibility for the cogeneration operation. If several power plants are bound to centrally managed clusters, it is called ''virtual power plant''. To operate smart grids optimally, new optimisation and model reduction techniques are necessary to get rid with the complexity. There is a great potential for the optimised management of CHPs, which is not yet used. Due to the fact that electrical and thermal demands do not occur simultaneously, a thermally driven CHP cannot supply electrical peak loads when needed. With the usage of thermal storage systems it is possible to decouple electric and thermal production. We developed an optimisation method based on mixed integer linear programming (MILP) for the management of local heat supply systems with CHPs, heating boilers and thermal storages. The algorithm allows the production of thermal and electric energy with a maximal benefit. In addition to fuel and maintenance costs it is assumed that the produced electricity of the CHP is sold at dynamic prices. This developed optimisation algorithm was used for an existing local heat system with 5 CHP units of the same type. An analysis of the potential showed that about 10% increase in benefit is possible compared to a typical thermally driven CHP system under current German boundary conditions. The quality of the optimisation result depends on an accurate prognosis of the thermal load which is realised with an empiric formula fitted with measured data by a multiple regression method. The key functionality of a virtual power plant is to increase the value of the produced power by clustering different plants. The first step of the optimisation concerns the local operation of the individual power generator, the second step is to calculate the contribution to the virtual power plant. With small extensions the suggested MILP algorithm can be used for an overall EEX (European Energy Exchange) optimised management of clustered CHP systems in form of the virtual power plant. This algorithm has been used to control cogeneration plants within a distribution grid. (author)

    Louisiana State University`s Energy Savings Performance Contract with CES/Way was a groundbreaking project that applied part-load cogeneration technology to a large university campus to meet chilled water and steam requirements for expansion needs. Simultaneously, the project provided these utilities at no additional out of pocket cost to the institution by using the innovative financing mechanism of performance contracting, in which project savings pay for the investment. In addition, the work is performed via a cogeneration system operating most of the year at part-load. This mechanical cogeneration project could also be termed a thermal cogeneration project, as it provides a dual thermal benefit from a single input energy source. Not only did the project achieve the projected energy savings, but the savings proved to be so dependable that the University opted for an early buyout of the project from CES/Way in 1994, after only about two years of documented savings.

    This article describes the development, calibration and validation of a combustion-cogeneration model for whole-building simulation. As part of IEA Annex 42, we proposed a parametric model for studying residentialscale cogeneration systems based on both Stirling and internal combustion engines. The model can predict the fuel use, thermal output and electrical generation of a cogeneration device in response to changing loads, coolant temperatures and flow rates, and control strategies. The model is now implemented in the publicly-available EnergyPlus, ESP-r and TRNSYS building simulation programs. We vetted all three implementations using a comprehensive comparative testing suite, and validated the model's theoretical basis through comparison to measured data. The results demonstrate acceptable-to-excellent agreement, and suggest the model can be used with confidence when studying the energy performance of cogeneration equipment in non-condensing operation.

    A co-generation plant for the combined production of electricity and heat has recently been installed on the CERN Meyrin site. This plant consists of: a gas turbine generator set (GT-set), a heat recovery boiler for the connection to the CERN primary heating network, as well as various components for the integration on site. A feasibility study was carried out and based on the argument that the combined use of natural gas -available anyhow for heating purposes- gives an attractively high total efficiency, which will, in a period of time, pay off the investment. This report will explain and update the calculation model, thereby confirming the benefits of the project. The results from the commissioning tests will be taken into account, as well as the benefits to be realized under the condition that the plant can operate undisturbed by technical setbacks which, incidentally, has not been entirely avoided during the first year of test-run and operation.

    The General Services Administration, through its National Capital Region, operates a district heating system - called the Heating Operation and Transmission District - that provides steam to approximately 100 government buildings in Washington, D.C. HOTD is examining a host of options that will improve its ability to provide reliable, environmentally sound, and cost-effective service to its customers. This report evaluates one of those options - cogeneration, a technology that would enable HOTD to produce steam and electricity simultaneously. The study concluded that, under current regulations, cogeneration is not attractive economically because the payback period (15 years) exceeds Federal return-on-investment guidelines. However, if the regulatory environment changes to allow wheeling (transmission of power by a non-utility power producer to another user), cogeneration would be attractive; HOTD would save anywhere from $38 million to $118 million and the investment would pay back in 7 to 10 years. Although incorporating cogeneration into the HOTD system has no strong benefit at this time, the report recommends that GSA reevaluate cogeneration in one or two years because Federal regulations regarding wheeling are under review. It also recommends that GSA work with the District of Columbia government to develop standards for cogeneration.

    In recent years gas Otto-cycle engines have become common for various applications in the field of power and heat generation. Gas engines are chosen sometimes even to replace diesel engines, because of their clean exhaust emission characteristics and the ample availability of natural gas in the world. The Austrian Jenbacher Energie Systeme AG has been producing gas engines in the range of 300 to 1,600 kW since 1960. The product program covers state-of-the-art natural gas engines as well as advanced applications for a wide range of alterative gas fuels with emission levels comparable to Low Emission (LEV) and Ultra Low Emission Vehicle (ULEV) standards. In recent times the demand for special cogeneration applications is rising. For example, a turnkey cogeneration power plant for a total 14.4 MW electric power and heat output consisting of four JMS616-GSNLC/B spark-fired gas engines specially tuned for high altitude operation has been delivered to the well-known European ski resort of Sestriere. Sestriere is situated in the Italian Alps at an altitude of more than 2,000 m above sea level. The engines feature a turbocharging system tuned to an ambient air pressure of only 80 kPa to provide an output and efficiency of each 1.6 MW and up to 40% {at} 1,500 rpm, respectively. The ever-increasing demand for lower pollutant emissions in the US and some European countries initiates developments in new exhaust aftertreatment technologies. Thermal reactor and Selective Catalytic Reduction (SCR) systems are used to reduce tailpipe CO and NO{sub x} emissions of engines. Both SCR and thermal reactor technology will shift the engine tuning to achieve maximum efficiency and power output. Development results are presented, featuring the ultra low emission potential of biogas and natural gas engines with exhaust aftertreatment.

    District energy systems are a major part of the energy use and delivery infrastructure of the United States. With nearly 6,000 operating systems currently in place, district energy represents approximately 800 billion BTU per hour of installed thermal production capacity, and provides over 1.1 quadrillion BTU of energy annually -- about 1.3% of all energy used in the US each year. Delivered through more that 20,000 miles of pipe, this energy is used to heat and cool almost 12 billion square feet of enclosed space in buildings that serve a diverse range of office, education, health care, military, industrial and residential needs. This Census is intended to provide a better understanding of the character and extent of district heating, cooling and cogeneration in the United States. It defines a district energy system as: Any system that provides thermal energy (steam, hot water, or chilled water) for space heating, space cooling, or process uses from a central plant, and that distributes the energy to two or more buildings through a network of pipes. If electricity is produced, the system is a cogenerating facility. The Census was conducted through surveys administered to the memberships of eleven national associations and agencies that collectively represent the great majority of the nation`s district energy system operators. Responses received from these surveys account for about 11% of all district systems in the United States. Data in this report is organized and presented within six user sectors selected to illustrate the significance of district energy in institutional, community and utility settings. Projections estimate the full extent of district energy systems in each sector.

    1993-07-01

    This report describes the results of a study of thermal energy storage (TES) systems integrated with combined-cycle gas turbine cogeneration systems. Integrating thermal energy storage with conventional cogeneration equipment increases the initial cost of the combined system; but, by decoupling electric power and process heat production, the system offers two significant advantages. First, electric power can be generated on demand, irrespective of the process heat load profile, thus increasing the value of the power produced. Second, although supplementary firing could be used to serve independently varying electric and process heat loads, this approach is inefficient. Integrating TES with cogeneration can serve the two independent loads while firing all fuel in the gas turbine. An earlier study analyzed TES integrated with a simple-cycle cogeneration system. This follow-on study evaluated the cost of power produced by a combined-cycle electric power plant (CC), a combined-cycle cogeneration plant (CC/Cogen), and a combined-cycle cogeneration plant integrated with thermal energy storage (CC/TES/Cogen). Each of these three systems was designed to serve a fixed (24 hr/day) process steam load. The value of producing electricity was set at the levelized cost for a CC plant, while the value of the process steam was for a conventional stand-alone boiler. The results presented here compared the costs for CC/TES/Cogen system with those of the CC and the CC/Cogen plants. They indicate relatively poor economic prospects for integrating TES with a combined-cycle cogeneration power plant for the assumed designs. The major reason is the extremely close approach temperatures at the storage media heaters, which makes the heaters large and therefore expensive.

    To solve the shortage of gas and steam supply in the small towns of the country, a new gas steam cogeneration system has been developed. On the basis of the fundamental research on the system, a demonstration gas steam cogeneration system has been designed. As the phase 1 of the project, a 75t/h demonstration CFB boiler for gas steam cogeneration has been erected and operated at Yangzhong Thermal Power Plant of China. This paper introduces the first 75t/h demonstration CFB boiler for gas steam cogeneration. Due to the need of gas steam cogeneration process, the boiler has the features of high temperature cyclone separation, high solid recycle ratio, staged combustion and an external heat exchanger adjusting bed temperature and heat load. The operation results show that the boiler has wide fuel adaptability and the heating value of the coal changes from 14MJ/Kg to 25MJ/Kg. The heat load changes from 85t/h to 28t/h while steam parameter is maintained at the normal conditions. The combustion efficiency of the boiler attain 98%. The boiler design and operation experiences may be a guide to the design and operation of larger CFB units in the future.

    Osaka Gas and Tokyo Gas have high expectations for natural-gas-fueled Solid Oxide Fuel Cell (SOFC) cogeneration systems. SOFC offers many advantages for on-site cogeneration systems, such as high electrical efficiency, high quality by-product heat and low emissions. They are now executing a joint development program with Westinghouse Electric Corporation (hereinafter called as WELCO). This program is aimed to verify a 25kW class SOFC cogeneration system. This system, which was modified by replacing previous zirconia porous support tube cells (PST cells) with newly designed air electrode supported cells (AES cells), commenced operation on March 21, 1995. The system has been successfully operated for 13,100 hours as of February 7, 1997. This paper presents the performance evaluation of the new AES cells and the results of system operation at WELCO.

    The basic design of a cogeneration facility implies much more than looking for a gas turbine generating set that matches the steam host heat demand, and making an economical evaluation of the project. Tractebel Energy Engineering (TEE) has designed, built and commissioned since the early nineties 350 MW of cogeneration facilities, mainly producing electricity and steam with natural gas fired gas turbines, which is the present most common option for industrial combined heat and power production. A standardized cogeneration design does not exist. Each facility has to be carefully adapted to the steam host's particular situation, and important technical issues have to be addressed at an early stage of plant design.

    In this paper, the topics of carbon dioxide recovery from cogeneration projects and related industrial usage of carbon dioxide will be covered from North American and international perspectives. The CO{sub 2} recovery discussion will largely focus on one particular technology, namely the application of proprietary monoethanolamine (MEA) solvents, which have a very satisfactory record of performance in the cogeneration and power production industries. The US Federal Energy Act, the impetus behind the development of such projects, will be discussed along with its impacts on the feasibility of U.S. projects. This subject would be reviewed for other developed countries and developing economies as well. Moreover, capital and operating costs and requirements will be summarized for such plants, plus existing CO{sub 2} recovery (from cogeneration) projects will be identified.

    A thermodynamic study of an 88.4 MW cogeneration plant located in the United States is presented in this paper. The feedstock for this actual plant is culm, the waste left from anthracite coal mining. Before combustion in circulating fluidized bed boilers, the usable carbon within the culm is separated from the indigenous rock. The rock and ash waste from the combustion process fill adjacent land previously scared by strip mining. Trees and grass are planted in these areas as part of a land reclamation program. Analyses based on the first and second laws of thermodynamics using actual operating data are first presented to acquaint the reader with the plant's components and operation. Using emission and other relevant environmental data from the plant, all externalities study is outlined that estimates the plant's effect on the local population. The results show that the plant's cycle performs with a coefficient of utilization of 29% and all approximate exergetic efficiency of 34.5%. In order to increase these values, recommended improvements to the plant are noted. In addition, the externality costs associated with the estimated SO{sub 2} and NOx discharge from the culm fed plant are lower (85-95%) than those associated with a similarly sized coal fed plant. The plant's cycle efficiencies are lower than those associated with more modern technologies; such as all integrated gas turbine combined cycle. However, given the abundant, inexpensive supply of feedstock located adjacent to the plant and the environmental benefit of removing culm banks, the plant's existing operation is unique from an economical and environmental viewpoint.

  15. Conceptual design phase of a district heating and cooling plant with cogeneration to serve James Madison University and the Harrisonburg Electric Commission

    A unique opportunity for cooperation and community development exists in Harrisonburg, Virginia. James Madison University, located in Harrisonburg, is undergoing an aggressive growth plan of its academic base which also includes the physical expansion of its campus. The City of Harrisonburg is presently supplying steam to meet a portion of the heating needs of the existing James Madison campus from a city owned and operated waste-to-energy plant. In an effort of cooperation, Harrisonburg and James Madison University have now negotiated an agreement for the city to provide all of the heating and cooling requirements of the new campus expansion. In another unique turn of events, the local electrical power distributor, Harrisonburg Electric Commission, approached the city concerning the inclusion of cogeneration in the project in order to reduce and maintain existing electric rates thus further benefiting the community. Through the cooperation of these three entities, the conceptual design phase of the project has been completed. The plant design developed through this process includes 3,000 tons of chilled water capacity, an additional 64,000 lb/hr of steam capacity and 2.5 MW of cogeneration capacity. This paper describes the conceptual design process for this interesting project.

    Adoption of decentralized energy technologies will be crucial in the evolving structure of energy markets and the magnitude of future greenhouse gas emissions. This detailed analysis of the adoption of engine cogeneration gives insights into organizational decision making regarding the diffusion of a cost effective decentralized energy technology. Detailed site information on over 600 UK cogeneration installations was collected and analyzed for the six year period during which UK energy markets were in the process of deregulation. A detailed examination using standard investment criteria of the cogeneration schemes indicated that over 70% of investments were of questionable economic value to adopters. This was because these installations were below the calculated minimum economic size threshold. A key determinant of this size threshold was found to be the fixed costs of maintenance. Analysis of the financing of installations revealed that the largest fraction of poor investments occurred in energy services agreements between suppliers and adopters. The policy implications for decentralized energy technologies of a minimum size threshold and poor investment decisions by early adopters are discussed. Further research aims to explore postulated explanations for the observed decline in early adoption of UK engine cogeneration.

    This guidebook focuses on cogeneration development. It is one of a series of four guidebooks recently prepared to introduce the energy developer to the federal, state and local agencies that regulate energy facilities in Idaho, Montana, Oregon, and Washington (the Bonneville Power Administration Service Territory). It was prepared specifically to help cogeneration developers obtain the permits, licenses and approvals necessary to construct and operate a cogeneration facility. The regulations, agencies and policies described herein are subject to change. Changes are likely to occur whenever energy or a project becomes a political issue, a state legislature meets, a preexisting popular or valuable land use is thought threatened, elected and appointed officials change, and new directions are imposed on states and local governments by the federal government. Accordingly, cogeneration developers should verify and continuously monitor the status of laws and rules that might affect their plans. Developers are cautioned that the regulations described herein may only be a starting point on the road to obtaining all the necessary permits.

    Developing safe, reliable, cost-effective, and efficient hydrogen-electricity co-generation systems is an important step in the quest for national energy security and minimized reliance on foreign oil. This project aimed to, through materials research, develop a cost-effective advanced technology cogenerating hydrogen and electricity directly from distributed natural gas and/or coal-derived fuels. This advanced technology was built upon a novel hybrid module composed of solid-oxide fuel-assisted electrolysis cells (SOFECs) and solid-oxide fuel cells (SOFCs), both of which were in planar, anode-supported designs. A SOFEC is an electrochemical device, in which an oxidizable fuel and steam are fed to the anode and cathode, respectively. Steam on the cathode is split into oxygen ions that are transported through an oxygen ion-conducting electrolyte (i.e. YSZ) to oxidize the anode fuel. The dissociated hydrogen and residual steam are exhausted from the SOFEC cathode and then separated by condensation of the steam to produce pure hydrogen. The rationale was that in such an approach fuel provides a chemical potential replacing the external power conventionally used to drive electrolysis cells (i.e. solid oxide electrolysis cells). A SOFC is similar to the SOFEC by replacing cathode steam with air for power generation. To fulfill the cogeneration objective, a hybrid module comprising reversible SOFEC stacks and SOFC stacks was designed that planar SOFECs and SOFCs were manifolded in such a way that the anodes of both the SOFCs and the SOFECs were fed the same fuel, (i.e. natural gas or coal-derived fuel). Hydrogen was produced by SOFECs and electricity was generated by SOFCs within the same hybrid system. A stand-alone 5 kW system comprising three SOFEC-SOFC hybrid modules and three dedicated SOFC stacks, balance-of-plant components (including a tailgas-fired steam generator and tailgas-fired process heaters), and electronic controls was designed, though an overall integrated system assembly was not completed because of limited resources. An inexpensive metallic interconnects fabrication process was developed in-house. BOP components were fabricated and evaluated under the forecasted operating conditions. Proof-of-concept demonstration of cogenerating hydrogen and electricity was performed, and demonstrated SOFEC operational stability over 360 hours with no significant degradation. Cost analysis was performed for providing an economic assessment of the cost of hydrogen production using the targeted hybrid technology, and for guiding future research and development.

    Waste Processors Management, Inc. (WMPI), along with its subcontractors Texaco Power & Gasification (now ChevronTexaco), SASOL Technology Ltd., and Nexant Inc. entered into a Cooperative Agreement DE-FC26-00NT40693 with the U. S. Department of Energy (DOE), National Energy Technology Laboratory (NETL) to assess the techno-economic viability of building an Early Entrance Co-Production Plant (EECP) in the United States to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase I is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase II is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase III updates the original EECP design based on results from Phase II, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania. The current report covers the period performance from July 1, 2003 through September 30, 2003. The DOE/WMPI Cooperative Agreement was modified on May 2003 to expand the project team to include Shell Global Solutions, U.S. and Uhde GmbH as the engineering contractor. The addition of Shell and Uhde strengthen both the technical capability and financing ability of the project. Uhde, as the prime EPC contractor, has the responsibility to develop a LSTK (lump sum turnkey) engineering design package for the EECP leading to the eventual detailed engineering, construction and operation of the proposed concept. Major technical activities during the reporting period include: (1) finalizing contractual agreements between DOE, Uhde and other technology providers, focusing on intellectual-property-right issues, (2) Uhde's preparation of a LSTK project execution plan and other project engineering procedural documents, and (3) Uhde's preliminary project technical concept assessment and trade-off evaluations.

    1998-07-01

    The disposal of industrial waste such as oil sludges, waste plastic, lubricant oils, paper and wood poses serious problems due to the ever increasing amount of material to be disposed of and to the difficulty in finding new dumping sites. The interest in energy recovery technologies is accordingly on the increase. In particular, large amounts of waste wood are simply burned or thrown away causing considerable environmental damage. In this context the co-generation technique represents one of the possible solutions for efficient energy conversion. The present paper proposes the employment of a Stirling engine as prime mover in a co-generation set equipped with a wood gasifier. A Stirling engine prototype previously developed in a joint project with Mase Generators, an Italian manufacturer of fixed and portable electrogenerators, is illustrated and its design is described.

    Customarily, electricity is generated in a utility power plant while thermal energy is generated in a heating/cooling plant; the electricity produced at the power plant is transmitted to the heating/cooling plant to power equipments. These two separate systems waste vast amounts of heat and result in individual efficiencies of about 35%. Cogeneration is the sequential production of power (electrical or mechanical) and thermal energy (process steam, hot/chilled water) from a single power source; the reject heat of one process issued as input into the subsequent process. Cogeneration increases the efficiency of these stand-alone systems by producing these two products sequentially at one location using a small additional amount of fuel, rendering the system efficiency greater than 70%. This report discusses cogeneration technologies as applied to wood fuel fired system.

    An apparatus and method for monitoring a process involve development and application of a statistically qualified neuro-analytic (SQNA) model to accurately and reliably identify process change. The development of the SQNA model is accomplished in two stages: deterministic model adaption and stochastic model modification of the deterministic model adaptation. Deterministic model adaption involves formulating an analytic model of the process representing known process characteristics, augmenting the analytic model with a neural network that captures unknown process characteristics, and training the resulting neuro-analytic model by adjusting the neural network weights according to a unique scaled equation error minimization technique. Stochastic model modification involves qualifying any remaining uncertainty in the trained neuro-analytic model by formulating a likelihood function, given an error propagation equation, for computing the probability that the neuro-analytic model generates measured process output. Preferably, the developed SQNA model is validated using known sequential probability ratio tests and applied to the process as an on-line monitoring system. Illustrative of the method and apparatus, the method is applied to a peristaltic pump system.

    The US military uses millions of Btu`s of thermal energy to heat, cool and deliver process thermal energy to buildings on military bases, much of which is transmitted through a pipeline system incorporating thousands of miles of pipe. Much of this pipeline system is in disrepair and is nearing the end of its useful life, and the boilers which supply it are old and often inefficient. In 1993, Brookhaven National Laboratory (BNL) proposed to SERDP a three-year effort to develop advanced systems of coupled diesel cogenerators and absorption chillers which would be particularly useful in providing a continuation of the services now provided by increasingly antiquated district systems. In mid-February, 1995, BNL learned that all subsequent funding for our program had been canceled. BNL staff continued to develop the Program Plan and to adhere to the requirements of the Execution Plan, but began to look for ways in which the work could be made relevant to Navy and DoD energy needs even without the extensive development plan formerly envisioned. The entire program was therefore re-oriented to look for ways in which small scale cogeneration and absorption chilling technologies, available through procurement rather than development, could provide some solutions to the problem of deteriorated district heating systems. The result is, we believe, a striking new approach to the provision of building services on military bases: in many cases, serious study should be made of the possibility that the old district heating system should be removed or abandoned, and small-scale cogenerators and absorption chillers should be installed in each building. In the remainder of this Summary, we develop the rationale behind this concept and summarize our findings concerning the conditions under which this course of action would be advisable and the economic benefits which will accrue if it is followed. The details are developed in the succeeding sections of the report.

    Cogeneration of heat and electricity is being considered by the South Dakota Soybean Processors for its facility in Volga, South Dakota, and a new facility to be located in Brewster, Minnesota. The Energy & Environmental Research Center has completed a feasibility study, with 40% funding provided from the U.S. Department of Energy's Jointly Sponsored Research Program to determine the potential application of firing biomass fuels combined with coal and comparative economics of natural gas-fired turbines. Various biomass fuels are available at each location. The most promising options based on availability are as follows. The economic impact of firing 25% biomass with coal can increase return on investment by 0.5 to 1.5 years when compared to firing natural gas. The results of the comparative economics suggest that a fluidized-bed cogeneration system will have the best economic performance. Installation for the Brewster site is recommended based on natural gas prices not dropping below a $4.00/MMBtu annual average delivered cost. Installation at the Volga site is only recommended if natural gas prices substantially increase to $5.00/MMBtu on average. A 1- to 2-year time frame will be needed for permitting and equipment procurement.

    Not so long ago, in the good old days, the energy supply to a health care facility was one of the most stable. The local utility provided what was needed at a reasonable cost. Now the energy industry is being deregulated. Major uncertainties exist in all parts of the energy industry. Since reasonably priced and readily available energy is mandatory for a health care facility operation, the energy industry uncertainties reverberate through the health care industry. This article reviews how the uncertainty of electric utility deregulation was converted to an opportunity to implement the ultimate energy conservation project--cogeneration. The project development was made essentially risk free by tailoring project development to deregulation. Costs and financial exposure were minimized by taking numerous small steps in sequence. Valley Medical Center, by persevering with the development of a cogeneration plant, has been able to reduce its energy costs and more importantly, stabilize its energy supply and costs for many years to come. This article reviews activities in two arenas, internal project development and external energy industry developments, by periodically updating each arena and showing how external developments affected the project.

    1980-09-01

    The primary objective of the TASE program is to determine the probable consequences to the environment and to public health and safety resulting from widespread implementation of major solar and renewable resource technologies. The specific principal Phase I objective is to determine the levels of residuals most likely to result throughout the complete energy cycle from the utilization of each of the solar and renewable resource technologies. Three basic technologies for recovering energy from M SW are considered in this study. These are: (1) direct combustion using a waterwall incinerator in which the heat from burning refuse is converted to steam by circulating water in steel tubes jacketing the interior of the incinerator; (2) manufacture of a relatively uniform shredded, pulverized or pelleted refuse-derived fuel (RDF) for supplemental firing in a utility boiler; and (3) pyrolysis or destructive distillation of MSW to extract a low-Btu fuel gas. While resource recovery and energy recovery systems can be installed independently, the processes described here include both energy and resource recovery systems as well as necessary pollution control equipment for gaseous emissions. To meet the Phase I objective, LBL staff have characterized the individual application associated with each general technology; calculated operational residuals generated by each application; determined the input capital requirements and, when possible, annual operating input requirements; and have identified the technical and institutional constraints for the widespread implementation of each application. A description is presented of the energy and material development cycle required for the implementation of each technology. The capital requirements are compiled and presented in a SEAS system format.

    2009-03-01

    Biomass-based ethanol and nuclear power are two viable elements in the path to U.S. energy independence. Numerous studies suggest nuclear power could provide a practical carbon-free heat source alternative for the production of biomass-based ethanol. In order for this coupling to occur, it is necessary to examine the interfacial requirements of both nuclear power plants and bioethanol refineries. This report describes the proposed characteristics of a small cogeneration nuclear power plant, a biochemical process-based cellulosic bioethanol refinery, and a thermochemical process-based cellulosic biorefinery. Systemic and interfacial issues relating to the co-location of either type of bioethanol facility with a nuclear power plant are presented and discussed. Results indicate future co-location efforts will require a new optimized energy strategy focused on overcoming the interfacial challenges identified in the report.

    We report the design and implementation of a complete electronics platform for conducting a quantum optics experiment that will be operated on board a 1U CubeSat (a 10 x 10 x 10 cm satellite). The quantum optics experiment is designed to produce polarization-entangled photon pairs using non-linear optical crystals and requires opto-electronic components such as a pump laser, single photon detectors and liquid crystal based polarization rotators in addition to passive optical elements. The platform provides mechanical support for the optical assembly. It also communicates autonomously with the host satellite to provide experiment data for transmission to a ground station. A limited number of commands can be transmitted from ground to the platform enabling it to switch experimental modes. This platform requires less than 1.5W for all operations, and is space qualified. The implementation of this electronics platform is a major step on the road to operating quantum communication experiments using nanosatellites.

    A high-throughput gasification system has been developed for the steam gasification of woody biomass to produce a fuel gas with a heating value of 475 to 500 Btu/SCF without using oxygen. Recent developments have focused on the use of bark and sawdust as feedstocks in addition to wood chips and the testing of a new reactor concept, the so-called controlled turbulent zone (CTZ) reactor to increase gas production per unit of wood fed. Operating data from the original gasification system and the CTZ system are used to examine the preliminary economics of biomass gasification/gas turbine cogeneration systems. In addition, a ''generic'' pressurized oxygen-blown gasification system is evaluated. The economics of these gasification systems are compared with a conventional wood boiler/steam turbine cogeneration system.

    This article describes the first major privatization effort to be completed at John F. Kennedy International Airport. The airport owner and operator, the Port Authority of New York and New Jersey, decided to seek private sector involvement in a capital-intensive project to expand and upgrade the airport`s heating and air conditioning facilities and construct a new cogeneration plant. Kennedy International Airport Cogeneration (KIAC) Partners, a partnership between Gas Energy Incorporated of New York and Community Energy Alternatives of New Jersey, was selected to develop an energy center to supply electricity and hot and chilled water to meet the airport`s growing energy demand. Construction of a 110 MW cogeneration plant, 7,000 tons of chilled water equipment, and 30,000 feet of hot water delivery piping started immediately. JFK Airport`s critical international position called for this substantial project to be developed almost invisibly; no interruption in heating and air conditioning service and no interference in the airport`s active operations could be tolerated. Commercial operation was achieved in February 1995.

    1998-07-01

    The facts that national electrical company Electricite de France (EDF) has a monopoly on electrical power production in France and an extensive installed base of nuclear power plants, explain the difficulty encountered in developing cogeneration technology in France. Cogeneration only really first appeared in this country in the early 1990's, with the liberalization of energy markets and the government's encouragement. Since then, the number of cogeneration plants has continuously increased and electrical generating capacity is now approximately 1,200 MWe. Turbine and reciprocating engines (most of which are natural gas fired) account respectively for about 55% and 45% of the installed power. Unlike other countries, such as Germany--which has about two thousand 500 kWe and smaller units--the future of low-power cogeneration in France is far from assured, and there are currently less than 10 such plants. To help develop this efficient technology for producing electrical power and hot water, the Ecole des Mines de Nantes purchased a 210 kWe cogeneration generator set in 1996. This facility provides all or part of the school's electrical and heat requirements during five months between November and March. This cogeneration facility is also used during the rest of the year to perform research experiments in the field of lean-burn natural gas combustion. Lastly, it is also used to provide training for industry in cogeneration technology. Within this context, work was undertaken to study the set's energy and emissions performance, in relation to such parameters as spark advance and air factor, and at various loads.

    Waste Processors Management, Inc. (WMPI), along with its subcontractors Texaco Power & Gasification (now ChevronTexaco), SASOL Technology Ltd., and Nexant Inc. entered into a Cooperative Agreement DE-FC26-00NT40693 with the U. S. Department of Energy (DOE), National Energy Technology Laboratory (NETL) to assess the technoeconomic viability of building an Early Entrance Co-Production Plant (EECP) in the United States to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase I is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase II is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase III updates the original EECP design based on results from Phase II, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania. The current report covers the period performance from January 1, 2003 through March 31, 2003. Phase I Task 6 activities of Preliminary Site Analysis were documented and reported as a separate Topical Report on February 2003. Most of the other technical activities were on hold pending on DOE's announcement of the Clean Coal Power Initiative (CCPI) awards. WMPI was awarded one of the CCPI projects in late January 2003 to engineer, construct and operate a first-of-kind gasification/liquefaction facility in the U.S. as a continued effort for the current WMPI EECP engineering feasibility study. Since then, project technical activities were focused on: (1) planning/revising the existing EECP work scope for transition into CCPI, and (2) ''jump starting'' all environmentally related work in pursue of NEPA and PA DEP permitting approval.

    The Atmospheric Fluidized-Bed Cogeneration Air Heater Experiment (ACAHE) sponsored by the US Department of Energy (DOE) was initiated to assess the performance of various heat-exchanger materials to be used in fluidized-bed combustion air heater systems. Westinghouse Electric Corporation, through subcontracts with Babcock & Wilcox, Foster Wheeler, and ABB Combustion Engineering Systems, prepared specifications and hardware for the ACAHE tests. Argonne National Laboratory contracted with Rockwell International to conduct tests in the DOE atmospheric fluidized-bed combustion facility. This report presents an overview of the project, a description of the facility and the test hardware, the test operating conditions, a summary of the operation, and the results of analyzing specimens from several uncooled and cooled probes exposed in the facility. Extensive microstructural analyses of the base alloys, claddings, coatings, and weldments were performed on specimens exposed in several probes for different lengths of time. Alloy penetration data were determined for several of the materials as a function of specimen orientation and the exposure location in the combustor. Finally, the data were compared with earlier laboratory test data, and the long-term performance of candidate materials for air-heater applications was assessed.

    The strategy for developing the HTGR system and introducing it into the energy marketplace is based on using the most developed technology path to establish a HTGR-Steam Cycle/Cogeneration (SC/C) Lead Project. Given the status of the HTGR-SC/C technology, a Lead Plant could be completed and operational by the mid 1990s. While there is remaining design and technology development that must be accomplished to fulfill technical and licensing requirements for a Lead Project commitment, the major barriers to the realization a HTGR-SC/C Lead Project are institutional in nature, e.g. Project organization and management, vendor/supplier development, cost/risk sharing between the public and private sector, and Project financing. These problems are further exacerbated by the overall pervading issues of economic and regulatory instability that presently confront the utility and nuclear industries. This document addresses the major institutional issues associated with the HTGR-SC/C Lead Project and provides a starting point for discussions between prospective Lead Project participants toward the realization of such a Project.

    Qualified Energy Conservation Bonds (QECBs) are federally-subsidized bonds that enable state, tribal, and local government issuers to borrow money to fund a range of energy conservation projects, including public building upgrades that reduce energy use by at least 20 percent, at very attractive borrowing rates and long terms. As part of the American Recovery and Reinvestment Act (ARRA), the City of Philadelphia received a $15 million QECB award from the U.S. Department of the Treasury (Treasury). The city leveraged $6.25 million of its QECB allocation to finance half of a $12.6 million initiative to upgrade the energy efficiency of City buildings. The upgrades to four city facilities are expected to deliver over $10 million of net savings, and are a major step towards achieving the city’s goal of reducing government energy consumption by 30 percent by 2015.

    The worldwide demand for potable water has been steadily growing and is projected to accelerate, driven by a continued population growth and industrialization of emerging countries. This growth is reflected in a recent market survey by the World Resources Institute, which shows a doubling in the installed capacity of seawater desalination plants every ten years. The production of desalinated water is energy intensive, requiring approximately 3-6 kWh/m3 of produced desalted water. At current U.S. water use rates, a dedicated 1000 MW power plant for every one million people would be required to meet our water needs with desalted water. Nuclear energy plants are attractive for large scale desalination application. The thermal energy produced in a nuclear plant can provide both electricity and desalted water without the production of greenhouse gases. A particularly attractive option for nuclear desalination is to couple a desalination plant with an advanced, modular, passively safe reactor design. The use of small-to-medium sized nuclear power plants allows for countries with smaller electrical grid needs and infrastructure to add new electrical and water capacity in more appropriate increments and allows countries to consider siting plants at a broader number of distributed locations. To meet these needs, a modified version of the International Reactor Innovative and Secure (IRIS) nuclear power plant design has been developed for the cogeneration of electricity and desalted water. The modular, passively safe features of IRIS make it especially well adapted for this application. Furthermore, several design features of the IRIS reactor will ensure a safe and reliable source of energy and water even for countries with limited nuclear power experience and infrastructure. The IRIS-D design utilizes low-quality steam extracted from the low-pressure turbine to boil seawater in a multi-effect distillation desalination plant. The desalination plant is based on the horizontal tube film evaporation design used successfully with the BN-350 nuclear plant in Aktau, Kazakhstan. Parametric studies have been performed to optimize the balance of plant design. Also, an economic analysis has been performed, which shows that IRIS-D should be able to provide electricity and clean water at highly competitive costs.

  12. High performance steam development. Final report, Phase No. 3: 1500{degree}F steam plant for industrial cogeneration prototype development tests

    SciTech Connect (OSTI)

    Duffy, T.; Schneider, P.

    1996-01-01

    As a key part of DOE`s and industry`s R&D efforts to improve the efficiency, cost, and emissions of power generation, a prototype High Performance Steam System (HPSS) has been designed, built, and demonstrated. The world`s highest temperature ASME Section I coded power plant successfully completed over 100 hours of development tests at 1500{degrees}F and 1500 psig on a 56,000 pound per hour steam generator, control valve and topping turbine at an output power of 5500 hp. This development advances the HPSS to 400{degrees}F higher steam temperature than the current best technology being installed around the world. Higher cycle temperatures produce higher conversion efficiencies and since steam is used to produce the large majority of the world`s power, the authors expect HPSS developments will have a major impact on electric power production and cogeneration in the twenty-first century. Coal fueled steam plants now produce the majority of the United States electric power. Cogeneration and reduced costs and availability of natural gas have now made gas turbines using Heat Recovery Steam Generators (HRSG`s) and combined cycles for cogeneration and power generation the lowest cost producer of electric power in the United States. These gas fueled combined cycles also have major benefits in reducing emissions while reducing the cost of electricity. Development of HPSS technology can significantly improve the efficiency of cogeneration, steam plants, and combined cycles. Figure 2 is a TS diagram that shows the HPSS has twice the energy available from each pound of steam when expanding from 1500{degrees}F and 1500 psia to 165 psia (150 psig, a common cogeneration process steam pressure). This report describes the prototype component and system design, and results of the 100-hour laboratory tests. The next phase of the program consists of building up the steam turbine into a generator set, and installing the power plant at an industrial site for extended operation.

  13. Energy conservation and electricity sector liberalization: Case-studies on the development of cogeneration, wind energy and demand-side management in the Netherlands, Denmark, Germany and the United Kingdom

    SciTech Connect (OSTI)

    Slingerland, S.

    1998-07-01

    In this paper, the development of cogeneration, wind energy and demand-side management in the Netherlands, Denmark, Germany and the United Kingdom are compared. It is discussed to what extent these developments are determined by the liberalization process. Three key liberalization variables are identified: unbundling, privatization and introduction of competition. The analysis suggests that unbundling prior to introduction of full competition in generation is particularly successful in stimulating industrial cogeneration; simultaneous introduction of competition and unbundling mainly stimulates non-cogeneration gas-based capacity; and introduction of competition in itself is likely to impede the development of district-heating cogeneration. Furthermore, it is argued that development of wind energy and demand-side management are primarily dependent on the kind of support system set up by policy makers rather than on the liberalization process. Negative impacts of introduction of competition on integrated resource planning and commercial energy services could nevertheless be expected.

    These guidelines were designed to assist National Rural Electric Cooperative Association staff and consultants involved in the implementation of Sections 201 and 210 of the Public Utilities Regulatory Policies Act (PURPA). The guidelines were structured to meet anticipated use as: a self-contained legal, technical and economic reference manual helpful in dealing with small power producers and cogenerators; a roadmap through some of the less obvious obstacles encountered by utilities interacting with small power producers and cogenerators; a starting point for those utilities who have not yet formulated specific policies and procedures, nor developed rates for purchasing power from small power producers and cogenerators; a discussion vehicle to highlight key issues and increase understanding in workshop presentations to rural electric cooperatives; and an evolutionary tool which can be updated to reflect changes in the law as they occur. The chapters in these Guidelines contain both summary information, such as compliance checklists, and detailed information, such as cost rate calculations, on regulatory requirements, operational considerations, and rate considerations. The appendices contain more specific material, e.g. rural electric cooperative sample policy statements. (LCL)

    We have experimentally observed the behaviour of cogenerated dusts in unmagnetized plasma produced using a bipolar pulsed dc power supply. In this experiment, the dust particles have been generated through sputtering of graphite cathode and were stratified between two electrodes. This stratification of dust clouds has obtained at a typical range of plasma parameters, namely, 650 V (peak-to-peak) with 0.2 mbar pressure. In above condition, we detected the Taylor-like instability at the interface of two dusty clouds with different densities. A very less dust density (void like) region inside the lesser dust density portion is also noted. Again, it has been observed that a self excited dust density wave propagates towards the higher density dust fluid inside the system as well as a stationary band structure of thin multiple layers of dust particles when we apply a higher voltage (750 V peak-to-peak). The wavelength, phase velocity, and frequency of the excited wave have also been estimated.

    This paper proposes a novel multifunctional energy system (MES), which cogenerates coke, hydrogen, and power, through the use of coal and coke oven gas (COG). In this system, a new type of coke oven, firing coal instead of COG as heating resource for coking, is adopted. The COG rich in H{sub 2} is sent to a pressure swing adsorption (PSA) unit to separate about 80% of hydrogen first, and then the PSA purge gas is fed to a combined cycle as fuel. The new system combines the chemical processes and power generation system, along with the integration of chemical conversion and thermal energy utilization. In this manner, both the chemical energy of fuel and thermal energy can be used more effectively. With the same inputs of fuel and the same output of coking heat, the new system can produce about 65% more hydrogen than that of individual systems. As a result, the thermal efficiency of the new system is about 70%, and the exergy efficiency is about 66%. Compared with individual systems, the primary energy saving ratio can reach as high as 12.5%. Based on the graphical exergy analyses, we disclose that the integration of synthetic utilization of COG and coal plays a significant role in decreasing the exergy destruction of the MES system. The promising results obtained may lead to a clean coal technology that will utilize COG and coal more efficiently and economically.

    BPA is considering whether to transfer (wheel) electrical power from a proposed privately-owned, combustion-turbine electrical generation plant in Oregon. The plant would be fired by natural gas and would use combined-cycle technology to generate up to 440 average megawatts (aMW) of energy. The plant would be developed, owned, and operated by Portland General Electric Company (PGE). The project would be built in eastern Oregon, just east of the City of Boardman in Morrow County. The proposed plant would be built on a site within the Port of Morrow Industrial Park. The proposed use for the site is consistent with the County land use plan. Building the transmission line needed to interconnect the power plant to BPA`s transmission system would require a variance from Morrow County. BPA would transfer power from the plant to its McNary-Slatt 500-kV transmission line. PGE would pay BPA for wheeling services. Key environmental concerns identified in the scoping process and evaluated in the draft Environmental Impact Statement (DEIS) include these potential impacts: (1) air quality impacts, such as emissions and their contributions to the {open_quotes}greenhouse{close_quotes} effect; (2) health and safety impacts, such as effects of electric and magnetic fields, (3) noise impacts, (4) farmland impacts, (5) water vapor impacts to transportation, (6) economic development and employment impacts, (7) visual impacts, (8) consistency with local comprehensive plans, and (9) water quality and supply impacts, such as the amount of wastewater discharged, and the source and amount of water required to operate the plant. These and other issues are discussed in the DEIS. The proposed project includes features designed to reduce environmental impacts. Based on studies completed for the DEIS, adverse environmental impacts associated with the proposed project were identified, and no evidence emerged to suggest that the proposed action is controversial.

    We report a numerical simulation for the phase diagram of a simple two dimensional model, similar to one proposed by Noro and Frenkel [J. Chem. Phys. \\textbf{114}, 2477 (2001)] for membrane proteins, but one that includes the role of the solvent. We first use Gibbs ensemble Monte Caro simulations to determine the phase behavior of particles interacting via a square-well potential in two dimensions for various values of the interaction range. A phenomenological model for the solute-solvent interactions is then studied to understand how the fluid-fluid coexistence curve is modified by solute-solvent interactions. It is shown that such a model can yield systems with liquid-liquid phase separation curves that have both upper and lower critical points, as well as closed loop phase diagrams, as is the case with the corresponding three dimensional model.

  13. Engine lubrication circuit including two pumps

    DOE Patents [OSTI]

    Lane, William H.

    2006-10-03

    A lubrication pump coupled to the engine is sized such that the it can supply the engine with a predetermined flow volume as soon as the engine reaches a peak torque engine speed. In engines that operate predominately at speeds above the peak torque engine speed, the lubrication pump is often producing lubrication fluid in excess of the predetermined flow volume that is bypassed back to a lubrication fluid source. This arguably results in wasted power. In order to more efficiently lubricate an engine, a lubrication circuit includes a lubrication pump and a variable delivery pump. The lubrication pump is operably coupled to the engine, and the variable delivery pump is in communication with a pump output controller that is operable to vary a lubrication fluid output from the variable delivery pump as a function of at least one of engine speed and lubrication flow volume or system pressure. Thus, the lubrication pump can be sized to produce the predetermined flow volume at a speed range at which the engine predominately operates while the variable delivery pump can supplement lubrication fluid delivery from the lubrication pump at engine speeds below the predominant engine speed range.

    Results of commercial operation of a world pioneer asynchronized turbogenerator T3FA-110 with a capacity of 11 MW and full air cooling at a cogeneration plant are presented. The turbogenerator developed jointly by the Electric Power Research Institute and the Elektrosila Company differs from traditional synchronous generators by the presence on the rotor of two mutually orthogonal windings, a two-channel reverse thyristor excitation system, and a special control system. The special features of design and control allow such generators to operate in the modes of both production and high consumption of reactive power at normal static and dynamic stability. This widens the range of regulation of the voltage level in the connected electric network and makes it possible to bring parallel-connected synchronous generators to optimum operation conditions. The generator can work without excitation for a long time at 70% load. Commercial operation of the pilot T3FA-110 turbogenerator started in December 2003 at TETs-22 of the Mosenergo Company and has proved its full correspondence to the design engineering parameters. A program of wide use of such turbogenerators in the United Power System of Russia (RAO 'EES Rossii' Co.) has been developed.

    The technology and economics of various wood energy systems available to the small industrial and commercial energy user are considered. This book is designed to help a plant manager, engineer, or others in a decision-making role to become more familiar with wood fuel systems and make informed decisions about switching to wood as a fuel. The following subjects are discussed: wood combustion, pelletized wood, fuel storage, fuel handling and preparation, combustion equipment, retrofitting fossil-fueled boilers, cogeneration, pollution abatement, and economic considerations of wood fuel use.

  20. Results of heat tests of the TGE-435 main boiler in the PGU-190/220 combined-cycle plant of the Tyumen' TETs-2 cogeneration plant

    SciTech Connect (OSTI)

    A.V. Kurochkin; A.L. Kovalenko; V.G. Kozlov; A.I. Krivobok

    2007-01-15

    Special features of operation of a boiler operating as a combined-cycle plant and having its own furnace and burner unit are descried. The flow of flue gases on the boiler is increased due to feeding of exhaust gases of the GTU into the furnace, which intensifies the convective heat exchange. In addition, it is not necessary to preheat air in the convective heating surfaces (the boiler has no air preheater). The convective heating surfaces of the boiler are used for heating the feed water, thus replacing the regeneration extractions of the steam turbine (HPP are absent in the circuit) and partially replacing the preheating of condensate (the LPP in the circuit of the unit are combined with preheaters of delivery water). Regeneration of the steam turbine is primarily used for the district cogeneration heating purposes. The furnace and burner unit of the exhaust-heat boiler (which is a new engineering solution for the given project) ensures utilization of not only the heat of the exhaust gases of the GTU but also of their excess volume, because the latter contains up to 15% oxygen that oxidizes the combustion process in the boiler. Thus, the gas temperature at the inlet to the boiler amounts to 580{sup o}C at an excess air factor a = 3.50; at the outlet these parameters are utilized to T{sub out} = 139{sup o}C and a{sub out} = 1.17. The proportions of the GTU/boiler loads that can actually be organized at the generating unit (and have been checked by testing) are presented and the proportions of loads recommended for the most efficient operation of the boiler are determined. The performance characteristics of the boiler are presented for various proportions of GTU/boiler loads. The operating conditions of the superheater and of the convective trailing heating surfaces are presented as well as the ecological parameters of the generating unit.

  1. Does Building a Relative Sunspot Number Make Sense? A Qualified 'Yes'

    E-Print Network [OSTI]

    Svalgaard, Leif

    2015-01-01

    Recent research has demonstrated that the number of sunspots per group ('active region') has been decreasing over the last two or three solar cycles and that the classical Relative Sunspot Number (SSN) no longer is a good representation of solar magnetic activity such as revealed by e.g. the F10.7 cm microwave flux. The SSN is derived under the assumption that the number of spots per group is constant (in fact, nominally equal to 10). When this is no longer the case (the ratio is approaching 5, only half of its nominal value) the question arises how to construct a sunspot number series that takes that into account. We propose to harmonize the SSN with the sunspot Group Count that has been shown to follow F10.7 very well, but also to include the day-to-day variations of the spot count in order to preserve both long-term and short-term variability.

    SciTech Connect (OSTI)

    Wirtshafter, R.; Abrash, M.; Koved, M.; Feldman, S.

    1982-05-01

    SERICPAC is a computer program developed to calculate average avoided cost rates for decentralized power producers and cogenerators that sell electricity to electric utilities. SERICPAC works in tandem with SERICOST, a program to calculate avoided costs, and determines the appropriate rates for buying and selling of electricity from electric utilities to qualifying facilities (QF) as stipulated under Section 210 of PURA. SERICPAC contains simulation models for eight technologies including wind, hydro, biogas, and cogeneration. The simulations are converted in a diversified utility production which can be either gross production or net production, which accounts for an internal electricity usage by the QF. The program allows for adjustments to the production to be made for scheduled and forced outages. The final output of the model is a technology-specific average annual rate. The report contains a description of the technologies and the simulations as well as complete user's guide to SERICPAC.

    A process for the treatment of geothermal residue includes contacting the pigmented amorphous silica-containing component with a depigmenting reagent one or more times to depigment the silica and produce a mixture containing depigmented amorphous silica and depigmenting reagent containing pigment material; separating the depigmented amorphous silica and from the depigmenting reagent to yield depigmented amorphous silica. Before or after the depigmenting contacting, the geothermal residue or depigmented silica can be treated with a metal solubilizing agent to produce another mixture containing pigmented or unpigmented amorphous silica-containing component and a solubilized metal-containing component; separating these components from each other to produce an amorphous silica product substantially devoid of metals and at least partially devoid of pigment. The amorphous silica product can be neutralized and thereafter dried at a temperature from about 25.degree. C. to 300.degree. C. The morphology of the silica product can be varied through the process conditions including sequence contacting steps, pH of depigmenting reagent, neutralization and drying conditions to tailor the amorphous silica for commercial use in products including filler for paint, paper, rubber and polymers, and chromatographic material.

    2011-04-14

    The Community Assessment Tool (CAT) for Public Health Emergencies Including Pandemic Influenza (hereafter referred to as the CAT) was developed as a result of feedback received from several communities. These communities participated in workshops focused on influenza pandemic planning and response. The 2008 through 2011 workshops were sponsored by the Centers for Disease Control and Prevention (CDC). Feedback during those workshops indicated the need for a tool that a community can use to assess its readiness for a disaster - readiness from a total healthcare perspective, not just hospitals, but the whole healthcare system. The CAT intends to do just that - help strengthen existing preparedness plans by allowing the healthcare system and other agencies to work together during an influenza pandemic. It helps reveal each core agency partners (sectors) capabilities and resources, and highlights cases of the same vendors being used for resource supplies (e.g., personal protective equipment [PPE] and oxygen) by the partners (e.g., public health departments, clinics, or hospitals). The CAT also addresses gaps in the community's capabilities or potential shortages in resources. This tool has been reviewed by a variety of key subject matter experts from federal, state, and local agencies and organizations. It also has been piloted with various communities that consist of different population sizes, to include large urban to small rural communities.

  16. Protoplanetary disks including radiative feedback from accreting planets

    E-Print Network [OSTI]

    Montesinos, Matias; Perez, Sebastian; Baruteau, Clement; Casassus, Simon

    2015-01-01

    While recent observational progress is converging on the detection of compact regions of thermal emission due to embedded protoplanets, further theoretical predictions are needed to understand the response of a protoplanetary disk to the planet formation radiative feedback. This is particularly important to make predictions for the observability of circumplanetary regions. In this work we use 2D hydrodynamical simulations to examine the evolution of a viscous protoplanetary disk in which a luminous Jupiter-mass planet is embedded. We use an energy equation which includes the radiative heating of the planet as an additional mechanism for planet formation feedback. Several models are computed for planet luminosities ranging from $10^{-5}$ to $10^{-3}$ Solar luminosities. We find that the planet radiative feedback enhances the disk's accretion rate at the planet's orbital radius, producing a hotter and more luminous environement around the planet, independently of the prescription used to model the disk's turbul...

  17. Including stereoscopic information in the reconstruction of coronal magnetic fields

    T. Wiegelmann; T. Neukirch

    2008-01-23

    We present a method to include stereoscopic information about the three dimensional structure of flux tubes into the reconstruction of the coronal magnetic field. Due to the low plasma beta in the corona we can assume a force free magnetic field, with the current density parallel to the magnetic field lines. Here we use linear force free fields for simplicity. The method uses the line of sight magnetic field on the photosphere as observational input. The value of $\\alpha$ is determined iteratively by comparing the reconstructed magnetic field with the observed structures. The final configuration is the optimal linear force solution constrained by both the photospheric magnetogram and the observed plasma structures. As an example we apply our method to SOHO MDI/EIT data of an active region. In the future it is planned to apply the method to analyse data from the SECCHI instrument aboard the STEREO mission.
